Monoelement and multielement standards are used for calibration. Sample collection, separation of suspended matter by filtration or centrifugating and sample preparation are described. The results obtained by filtration and by centrifuging are compared. Interferences in evaluation of the gamma-spectra and their influence on the results are discussed. Systematic errors are detected by participation in ring analysis.en0022-4081Journal of radioanalytical chemistry19812335343Springerhttp://doku.b.tu-harburg.de/doku/lic_ohne_pod.phpTrace element determination in suspended matter and in sediments by instrumental neutron activation analysisJournal Articleurn:nbn:de:gbv:830-tubdok-461610.15480/882.38711420/38910.1007/BF0252221910.15480/882.387930767670Other
